The LTC3864EDE#TRPBF is a synchronous step-down DC/DC controller integrated circuit (IC) manufactured by Analog Devices. It is designed for driving N-channel MOSFETs in high-efficiency multiphase power supplies. With a wide input voltage range and versatile operation, this IC is suitable for various applications, including industrial, automotive, telecom, and server systems. Here, we present an overview of the LTC3864EDE#TRPBF along with its key features.
The LTC3864EDE#TRPBF IC operates using a constant frequency, current-mode architecture, enabling a very low duty cycle of up to 0.5%. It supports an input voltage range from 4.5V to 38V, allowing it to handle a wide range of supply voltages. This flexibility makes it suitable for both 12V and 24V systems.
One notable feature of the LTC3864EDE#TRPBF is its ability to support phase spreading, thereby reducing both input and output current ripple. This phase spreading feature also prevents the need for an external phase-locked loop (PLL) to synchronize multiple ICs. As a result, the IC reduces output voltage ripple and improves electromagnetic interference (EMI) performance.
To enhance system reliability, the LTC3864EDE#TRPBF incorporates a wide range of built-in protection features
